Application file'd August 16, 1920. Serial No. 403,773.

To'all whom it may concern:

Be it. known that I, ARLINGTON MOORE, a citizen of the United States, and a resident of Boston, county of Sufl'olk, State of Massachusetts, have invented an Improvement in Paper Containers, of which the following is a specification.

The present invention relates to paper containers, or containers made of suitable fibrous material, which will usually be coated with a water-proof material, or have such material incorporated therein, so that the container will hold liquids indefinitely.

More specifically the present invention relates to a formof container, which may be provided with a practically permanently connectedtclosure, at its top, whlch is adapted-to be moved rotatably, to bring a port therein into-register with a discharge port in the side wall, or neck of the container, so that the liquid therein may be poured from the container, and which, whenin a position in which the ports are. out of register, will entirely prevent the escape of liquid from the container, past the cap. I

In a container of this character, as the cap is preferably permanently connected during the process of manufacture, the container is filled through the bottom and, after filling, the bottom is pressed: into place and sealed, and a feature of the present invention is to provide a form of container, having the above described characteristics, which will permit a plurality of containers of like form to be nested, so that a large number may be packed in a comparatively small space.

One of the chief diflicultiesin nesting articles of this character especially if they are waterproofed with substances like paraifin or wax, is that they are liable to'adhere, so

uently seriously damaged, and in this connection, one'of the features of the presentjnvention consists in providing a construction which not only embodies the feature above referred to, but is also constructed so that, when a plurality thereof are nested, they ily separated, and, in case ofadhesion at points of contact, the adhesionmay be read ilybroken without damage to the container. To this end thecap of thecontainer may provided "with a reenforcing rib or bead, which-is'arranged to seat against a shoulder may always be read-.

" main body a, of the container is of conical form and its side-wall end-portion, at its base or large end, is bent inward on itself a and moulded to form an annular internal groove a, into which a stiff bottom I) is adapted to be sprung, and which is sealed by bending in the flange beyond the groove, this operation being performed after the can has been filled.

A ledge, or shoulded a is formed in the side wall of the can at itssmaller end, from which point the wall is extended cylindrically, to form a neck a and a closure for this end of the can is provided, which comprises a disc 0 and a cylindrical tubular flange portion 01, one end portion of the latter being folded over or convoluted with an edge flange a, formed on the disc, said against the outer side of the shoulder (E, that they are difiicult to. separate when they are to be used, and are and the inner side of the disc portion 0 of the closure seats against the edge or rim of the neck.- -A permanent connection is formed between the closure and theneck of' indenting a pair of anand corresponding ribs,

The connection thus formed permits the rotation, but not the removal of the closure, and, to'enable the contents of the container while the closure is in this being pressed inwardly to be removed, the'flange portion of the closure and the neck of the container are respectively provided with apertures d and a midway between the grooves, arranged to be brought into register by rotation of the closure. lVhen the closure is in such a position that the apertures are out of register, the escape of liquid between the neck of the container and the flange of the closure is prevented by the close engagement of the flange with the neck, at the indented portions, and the seating of the edge of the flange on the shoulder a and of the disc portion on the edge of the neck.

The upper groove (Z increases the frictional engagement of the closure with the container, thereby preventing liability of accidental movement of the closure thereon, and as it is formed in proximity to the rim of the container, it also substantially strengthens the edge portion thereof.

As shown in the drawing, the outer side of the connecting rib d is tapered to'correspond to the taper of the side wall of, the container, so that, when several containers are to be nested, the top surface of the rib of one will seat against the shoulder a of the other, and the side of the rib on the one will seat against theadjacent inner surface of the other, as shown in Fig. 2.

In this position, side of one container will be engaged with the inner surface of the other container, except at the rib (1, unless it tilts sidewiise slightly, in which case it will engage the inturned rib o of the other container. looseness is thus permitted which enables any adhesion, due to nesting, to be readily broken. Also, as the full weight of one against the other is borne by the engage- 'ment'- of the rib d injury due tonesting is practically avoided.

no portion'of the outer with the shoulder, a

necting rib at the junction of said disk and flange adapted to seat against the internal shoulder and the adjacent interior surface of a similarcontainer, when nested therein.

2. A paper container having a tapering side wall and a neck of uniform-diameter extending from the smaller end thereof, a closure for said neck, comprising a disk and a flange fitting the exterior of said neck and havin an interlocking connection with said disk forming a head at the edge and top side of the disk, the outer surface of the bead being continuous with the outer surface of the flange and tapering correspondingly to the side wall of the container to permit the head to seat against the interior surface ofa similar container adjacent its neck.

3. A paper container having a tapering side wall and a neck of uniform diameter extending from the smaller end thereof, a closure for said neck, comprising an end cap and a side wall having adjacent portions thereof folded together to form a head on the outside of the cap at its edge, the side of said head being continuous with the outer surface of the side wall of the closure and adapted to seat againstthe interior surface of a similar container, nested.

In testimony whereof, I have signed my name to this specification.
